This plugin shows the number of user subscriptions and unsubscriptions for each month.It is based on the idea of the User Statistics By Month plugin http://forums.phplist.com/viewtopic.php?f=7&t=18860, but has been redeveloped fixing some problems, including empty months and improving the chart.

A new release of the plugin that includes French translation in UTF-8 format as well as the default ISO-8859-1. So, if you have modified the French language_info file to use UTF-8 then the plugin's captions should now be displayed correctly. This requires the latest (20120828) CommonPlugin to be installed.

A new release of the plugin that fixes a problem with the download button introduced when I merged the three User plugins. The button always downloaded the user details, even when on the history tab or the subscriptions tab.
